"Great people-watching" on the River Walk makes it "worth the wait" for an outside table at this "casual" steak-and-seafood favorite, known for its "enjoyable" "amalgamation of Southwest border" fare including "must-have" "guacamole made tableside" and "prickly pear margaritas"; though its rep keeps the "tight" interior "crowded" and "loud", it's always a "best bet" "if you only have one night" in town.
